Best way to remove rust from coin mechs?
Necro:
Just as a bit of information to people, WD-40 is NOT a lubricant. It actually stands for Water Displacement Formula 40 or something like that. It was developed to displace water and prevent corrosion - the mild lubrication is a byproduct of that. Overtime, it actually acts OPPOSITE (as alluded to above) of a lubricant because it gunks up.
Now, not saying this is a good or the best way but there's always this: http://www.instructables.com/id/Electrolytic-Rust-Removal-aka-Magic/
Be careful if you attempt that however, as when we tries something like it when I was a kid we blew up the jar we had the liquid in :).

I soaked two of the coin mechs overnight for 8 hours and then scrubbed them with the brass brush this morning. I washed and blow dried them with a hair dryer afterwards. They came out amazingly great. Cosmetically, I wasn't really concerned about how they looked, but more of how they functioned. (It's just a bonus that they look great too.)
Originally, the return mechanism, when pushed in, was super hard to do. Now, it's like butter. It's just like new and coins no longer get stuck.
Thanks again for the tips.

This stuff is pretty strong so it's advisable to use gloves, eye protection (in case of a splash of this stuff in your eyes) and have adequate ventilation for the fumes.
